Elvis Presley's Graceland attraction has said two of the King's planes will be staying at the Tennessee mansion permanently, apparently ending confusion over their future.

Graceland released a statement saying the Lisa Marie and the Hound Dog II, two custom-designed planes once owned by Presley, will remain at the Memphis tourist attraction centred on the life and career of the late singer.

The planes were once used by Presley for travel to performances after he bought them in the 1970s.

The larger plane, a Convair 880 named after his daughter Lisa Marie, is like a customised flying limousine, complete with a large bed, stereo system, conference room and gold-plated bathroom fixtures.

It was renovated after Presley bought it from Delta Air Lines and the singer took his first flight on it in November 1975.

When he died on August 16 1977, his pilot flew the Lisa Marie to California to pick up Presley's ex-wife Priscilla, to bring her back to Memphis.

The Hound Dog II, a smaller JetStar plane, was also used by Presley.
